  <meta name="assert" content="This test checks that the ::selection pseudo-element must be drawn below an absolutely positioned element. In this test, such absolutely positioned element is a preceding sibling element.">

  /* We first create an empty range */
  targetRange.selectNodeContents(document.getElementById("test"));
  /* Then we set the range boundaries to the children of div#test */
  window.getSelection().addRange(targetRange);
  /* Finally, we now select such range of content */

  <p>Test passes if "Text sample" is green and if its background color is yellow.
